A new steganography technique based on genetic algorithm

As technology grows, it affect our daily lives becomes more penetrating. Our private information may be violated when communications media are used, to achieve security this paper was based on a new technique of steganography using cryptography, color model and genetic algorithm. First, the secret text encrypted with advanced encryption standard (AES) Second, hiding applied in two stages. cover-image converted hue saturation intensity (HSI) select one models, then divide into group blocks them by least significant bit (LSB) method specified bytes randomly, algorithm that calculates peak signal-to-noise-ratio (PSNR) for all after process thus obtain best value PSNR optimal block. includes final results first stage random distribution according The mean square error (MSE) measures were adopted prove accuracy efficiency results.
